REPET Algorithm - Background Music Separation Using Auto-correlation

Pre-requisites:

  1. Knowing the discrete Fourier transform (DFT);
  2. Knowing the auto-correlation calculation for discrete series.

This is a note for Zafar Rafii’s REpeating Pattern Extraction Technique (REPET) algorithm in its basic form. REPET is a super-simple algorithm which could separate human voice from accompanied music, although it is effective only in typical cases when background music is highly repetitive.
